BACKGROUND 1. Field

The disclosure relates to an electronic device including a flexible display capable of changing the size of a display area, and a method for controlling the same.

2. Description of Related Art

An electronic device (for example, a mobile phone) can output stored information as a sound or an image. With the increase of the degree of integration of electronic devices and the popularization of hyper-speed and high-capacity wireless communication, recently, a single mobile communication terminal has various functions. For example, an entertainment function, such as a game, a multimedia function, such as reproducing music/moving images, a communication and security function for mobile banking, a scheduling function, an electronic wallet function, etc. are integrated into a single electronic device, in addition to a communication function.

Electronic devices are normally equipped with a planar plate-type display device and a battery, and have a bar-type, folder-type, or sliding-type exterior depending on the shape of the display device or the battery. Electronic devices having a large screen have recently appeared such that users can watch images comfortably.

In order to conveniently carry such electronic devices having a large screen, electronic devices employing a flexible display (or variable display) have been commercialized. An electronic device may include a flexible display such that various screens can be provided visually through the flexible display. The flexible display may include a display panel and a display driver integrated circuit (DDI) for driving the panel. The DDI mounted on the electronic device may receive display data from a processor and drive the display panel accordingly.

The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

SUMMARY

Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide an electronic device including a flexible display may output an application, which is being executed, on the flexible display. At least a partial surface of the flexible display may be arranged on the front and rear surfaces of the electronic device so as to form a curved line.

According to various embodiments, the screen of the application may be configured such that, for example, when a movement of a structure that forms the electronic device changes the screen to an open or closed state, the size of the display area is changed.

For example, in response to a change in size of the displayed screen area, the display method or arrangement of respective objects may vary. If respective objects are displayed identically without reflecting the attributes thereof in spite of a change in size of the screen area displayed by the flexible display, the user experience (UX) may degrade.

According to various embodiments, an electronic device may add an attribute to objects displayed on the screen in various situations in which the screen size of the flexible display is changed, and may display the objects on the screen on the basis of the attribute.

Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments.

Referring to FIG. 2, the electronic device 200 may include a display 212 (for example, the display 112 of FIG. 1A or a flexible touchscreen display layer); a first structure 210 (for example, the first structure 110 of FIG. 1A); a first plate 211; a second structure 220 (for example, the second structure 120 of FIG. 1A); a second plate 221; a printed circuit board 230; a first support member 240 (for example, a rear case); a first rear plate 250; a first hinge plate 261; a roller 262; a second hinge plate 264; or a second rear plate 280 (for example, a rear window). In some embodiments, at least one of the constituent elements of the electronic device 200 (for example, the first support member 240 or the first rear plate 250) may be omitted, or the same may further include another constituent element.

The display 212 may include a first surface 212 a, a second surface 212 b, and a third surface 212 c, and the display area (for example, active area) of the screen may be changed on the basis of the exposed area according to various embodiments. The first surface 212 a and the third surface 212 c may form a planar surface, and the second surface 212 b may form a curved surface. In an embodiment, the exposed area of the display 212 may vary depending on a movement of the first structure 210 with regard to the second structure 220, and the second surface 212 b or the third surface 212 c may form substantially the same planar surface with the first surface 212 a successively or partially. For example, the second surface 212 b or the third surface 212 c may be exposed to the outside successively or selectively.

The first structure 210 may include a first plate 211. The first structure 210 may be made of a metallic material and/or a nonmetallic material (for example, polymer), for example. The display 212 (for example, the first surface 212 a) may be coupled to one surface of the first plate 211, and the printed circuit board 230 may be coupled to the other surface thereof. The first plate 211 may be connected to one side of a multi-bar 263 which is at least connected to the second surface 212 b of the display 212. The second structure 220 may fix the second hinge plate 264, and the first structure 210 may move while being guided by the second hinge plate 264.

The first hinge plate 261 may support the multi-bar 263 when the display 212 is expanded. For example, if the display 212 is expanded, the multi-bar 263 may be positioned on substantially the same plane with the first plate 211 while being supported by the first hinge plate 261. In an embodiment, when the display 212 is not expanded, the multi-bar 263 may be contained inside the second structure 220 and positioned substantially in parallel with the first plate 211, and may maintain the shape of a planar plate while being supported by the second hinge plate 264. The first hinge plate 261 and the first hinge plate fixing portion 261 a may be formed integrally. The first hinge plate fixing portion 261 a may be connected to the second hinge plate fixing portion 264 a formed on the second hinge plate 264. In some embodiments, the first hinge plate 261 or the second hinge plate 264 may be fixed inside the second structure 220 so as to guide the movement of the first structure 210 with regard to the second structure 220.

The roller 262 may guide or support the multi-bar 263 such that the same can move with a predetermined radius. The roller 262 may be connected to the second hinge plate fixing portion 264 a or the first hinge plate 261. For example, when the first plate 211 (for example, the first structure 110) moves with regard to the second structure 210, the roller 262 may rotate and guide the multi-bar 263 to the outside or inside of the second structure 220.

The multi-bar 263 may include multiple straight rods. The multi-bar 263 may support at least a part of the second surface 212 b of the display 212. The multi-bar 263 may be contained in the second structure 220 while being partially supported by the second hinge plate 264, and the other side of the multi-bar 263 may be connected to the first structure 210.

The second hinge plate 264 may support the third surface 212 c of the display 212. The second hinge plate 264 may support the multi-bar 263, when the display 212 is expanded, such that the same maintains the shape of a planar plate. The second hinge plate 264 may be formed as a component separate from the second hinge plate fixing portion 264 a. The second hinge plate 264 may, while being fixed to the second structure 220, guide the sliding movement of the first structure 210 with regard to the second structure 220 by using the second hinge plate fixing portion 264 a.

The second structure 220 may be formed to surround at least a part of the first structure 210, the second hinge plate 264, the multi-bar 263, and the like. According to an embodiment, the second structure 220 may include a second plate 221; a first sidewall 221 a extending from the second plate 221; a second sidewall 221 b extending from the first sidewall 221 a and from the second plate 221; and a third sidewall 221 c which extends from the first sidewall 221 a and from the second plate 221, and which is parallel with the second sidewall 221 b. The second structure 220 may contain a constituent element such as an antenna in a space which does not overlap the multi-bar 263. The second structure 220 may include a second rear plate 280 which covers at least a part of the third surface 212 c of the display 212.

The second rear plate 280 may include a material which does not transmit light when there is no need to display information on the third surface 212 c of the display 212. As another example, the second rear plate 280 may be made of a material which transmits light such that information displayed on the third surface 212 c is visible from the outside even when the display 212 is partially contained in the second structure 220. The second rear plate 280 may be formed integrally with the second structure 220.

The first support member 240 may be arranged between the printed circuit board 230 and the first rear plate 250.

The printed circuit board 230 may have a processor, a memory, and/or an interface mounted thereon.

For example, the interface may connect the electronic device 200 with an external electronic device electrically or physically, and may include a USB connector, an SD card/MMC connector, or an audio connector.

FIG. 3 is a side view of an electronic device 300 according to an embodiment of the disclosure.

FIG. 4 is a top view of a part of the inner surface of the second plate 321 of the electronic device according to an embodiment of the disclosure.

It is to be noted that, in the following description of the embodiment with reference to FIG. 3 and FIG. 4, illustration of a sidewall of the second structure (for example, the second sidewall 121 b or the third sidewall 121 c of the second structure 120 in FIG. 1A) is omitted.

Referring to FIG. 3 and FIG. 4, the electronic device 300 (for example, the electronic device 100 or 200 of FIG. 1A or FIG. 2) may include a first structure 310 (for example, the first structure 210 of FIG. 2), a multi-bar 363 (for example, the multi-bar 363 of FIG. 2) connected to the first structure 310, or a second plate 321 (for example, the second plate 221 of FIG. 2) which at least partially surrounds the first structure 310 and the multi-bar 363. In some embodiments, the second plate 321 may have an end configured in a curved shape so as to form at least a part of the first sidewall (for example, the first sidewall 212 a of FIG. 1A).

According to an embodiment, the multi-bar 363 may extend to or be contained in the space between the second plate 321 (or the first sidewall 221 a of FIG. 2) and the first structure 310 together with the display (for example, the display 212 of FIG. 2 or the flexible touchscreen display layer). For example, at least in the closed state illustrated in FIG. 1A, the multi-bar 363 or a partial area of the display supported by the multi-bar 363 (for example, the bendable portion of the display 112 of FIG. 1A) may extend to the space between the second plate 321 (or the first sidewall 221 a of FIG. 2) and the first structure 310.

According to various embodiments, there may be provided, on the inner surface of the second plate 321, a conductive pattern 411 and a wire 413 (for example, a flexible printed circuit board) connecting the conductive pattern 411 with the printed circuit board 230. In an embodiment, the conductive pattern 411 may function as an antenna of the electronic device 300. In some embodiments, the conductive pattern 411 may face at least a part of a surface (for example, inner surface) of the second plate 321, for example, a trough provided by the second structure 120 or 220 of FIG. 1 or FIG. 2 (for example, the trough 220 a of FIG. 2). A capacitive element may be arranged on the surface of the second plate 321, or a dielectric protrusion (for example, “511” in FIG. 5 or FIG. 6) or a metallic protrusion may be formed thereon.

The dielectric protrusion 511 will be described in more detail with reference to FIG. 5 and FIG. 6. FIG. 5 is a magnified sectional view of part “E1” of FIG. 3. FIG. 6 is a magnified perspective view of part “E2” of FIG. 4.

FIG. 5 is a magnified sectional view of part “E1” of FIG. 3 according to an embodiment of the disclosure.

FIG. 6 is a magnified perspective view of part “E2” of FIG. 4 according to an embodiment of the disclosure.

Referring to FIG. 5 and FIG. 6 additionally, the dielectric protrusion 511 may be substantially formed on a surface (for example, inner surface) of an end of the second plate 321. In some embodiments, the dielectric protrusion 511 may keep facing a part of the display 512 (for example, the third surface 212 c of the display in FIG. 2) inside the second structure (for example, the second structure 220 of FIG. 2). For example, the dielectric protrusion 511 may keep facing a part of the display 512 inside the second structure regardless of whether the electronic device 300 (for example, the electronic device 101 of FIG. 1A) is in a closed state or in an open state. According to an embodiment, when the dielectric protrusion 511 generates a touch input (or hovering input) on the display 512 or the flexible touchscreen display layer (for example, the display 212 of FIG. 2), the electronic device 300 (or the processor of the electronic device 300) may sense a screen size change in real time by sensing a change in the touch coordinate input to the touch panel of the display 512. For example, when the dielectric protrusion 511 generates a touch input or a hovering input on the display 512 or the flexible touchscreen display layer (for example, the display 212 of FIG. 2), the electronic device 300 may detect the position or coordinate in which the touch input or hovering input has occurred.

For example, a movement of the first structure 310 may change the relative position of the dielectric protrusion 511 with regard to the display 512, and the electronic device 300 or the processor may detect the position (or position change) of the dielectric protrusion 511 by using the touchscreen function of the display 512 (or by using an additional sensing device). The electronic device 300 or the processor may calculate the area of the exposed display from the detected position or coordinate of the dielectric protrusion 511.

FIG. 7 is a top view of another example of the second plate 721 of an electronic device 101 according to an embodiment of the disclosure.

FIG. 8 is a diagram illustrating an operation of an electronic device 101 according to an embodiment of the disclosure.

Referring to FIG. 7 and FIG. 8, the second plate 721 may include a conductive plate 723 provided on the inner surface thereof, and the conductive plate 723 may include at least one of a ground portion 723 a, an extension portion 723 b extending from the ground portion 723 a, and protrusion portions 723 c and 723 d formed on the extension portion 723 b. The protrusion portions 723 c and 723 d may, for example, provide a function similar to that of the dielectric protrusion 511 of FIG. 5. For example, the position (or coordinate) of the protrusion portions 723 c and 723 d may be detected through the touchscreen function of the display.

According to various embodiments, the conductive plate 723 may include at least one of a first protrusion portion 723 c or a second protrusion portion 723 d. In an embodiment, when the electronic device (for example, the electronic device 101 of FIG. 1A) is in the closed state (for example, when an end of the display 712 is positioned at the point indicated by “P1”), the first protrusion portion 723 c may be positioned to face a part of the display 712, and the second protrusion portion 723 d may be positioned to face another part of the display 712. The electronic device or the processor of the electronic device may detect the position (or coordinate) of the first protrusion portion 723 c or the second protrusion portion 723 d by using the touchscreen function of the display 712, and may determine that the electronic device is in the closed state on the basis of the detected position.

According to various embodiments, if the electronic device or the first structure (for example, the first structure 110 of FIG. 1A) gradually moves to the open state, the display 712 may move to a position away from the first protrusion portion 723 c. According to an embodiment, when the electronic device or the first structure has moved out of the closed state, the display 712 may detect the position of the second protrusion portion 723 d through the touchscreen function, but the position of the first protrusion portion 723 c may not be detected. For example, when the electronic device or the first structure has moved out of the closed state or has reached the open state (for example, when an end of the display 712 is positioned at the point indicated by “P2”), the electronic device or the processor of the electronic device may detect the position (or coordinate) of the second protrusion portion 723 d by using the touchscreen function of the display 712, and may calculate the exposed area of the display on the basis of the detected position or coordinate of the second protrusion portion 723 d.

FIG. 9 is a diagram illustrating another operation of an electronic device according to an embodiment of the disclosure.

FIG. 10 is a diagram illustrating another operation of an electronic device according to an embodiment of the disclosure.

FIG. 11 is a diagram illustrating still another operation of an electronic device according to an embodiment of the disclosure.

The operations illustrated in FIG. 9 to FIG. 11 may include an operation of detecting the closed state or open state of the first structure (for example, the first structure 210 of FIG. 2), for example, the display 912 (for example, the display 212 of FIG. 2) by using a detection element and a detection target. The detection element may include, for example, a hall sensor (for example, the hall sensors 911 a, 911 b, and 911 c of FIG. 9 or FIG. 10), a mechanically operating switch element (for example, the switch elements 1113 a and 1113 b of FIG. 11), or a photodetector, and the detection target may vary depending on the kind of the detection element. For example, when a hall sensor is used as the detection element, the detection target may include a magnet (for example, the magnet 913 of FIG. 9). As another example, when a mechanical switch element is used as the detection element, the detection target may include a recess or a protrusion (for example, the recesses 111 a and 111 b of FIG. 11) which can engage with or interfere with the switch element. As another example, when a photodetector is used as the detection element, the detection target may include an optical pattern. If such a detection element is mounted on the first structure or the display (for example, the first structure 110 or the display 112 in FIG. 1A), the detection target may be mounted (or formed) on the second structure (for example, the second structure 120 of FIG. 1A). In some embodiments, the detection element may be mounted the second structure, and the detection target may be mounted on the first structure.

Referring to FIG. 9 and FIG. 10, at least one of the hall sensors 911 a, 911 b, and 911 c may be mounted as a detection element on the second plate 921 (for example, the second plate 221 or the second structure 220 in FIG. 2), and at least one magnet 913 may be mounted on as a detection target on the display 912 (or the first plate 211 of FIG. 2). According to an embodiment, the three hall sensors 911 a, 911 b, and 911 c may be mounted on the second plate 921, and the one magnet 913 may be mounted on a structure connected to the display 912. For example, if the first structure (for example, the first structure 110 of FIG. 1A) or the display 912 moves, the magnet may move so as to correspond thereto.

According to various embodiments, when the electronic device is in the closed state (for example, the state illustrated in FIG. 1A), the magnet 913 may be positioned to face the first hall sensor 911 a. For example, if the first hall sensor 911 a senses the magnet 913, the electronic device (or the processor) may confirm the closed state. When the electronic device is opened or when the electronic device has reached the open state (for example, the state illustrated in FIG. 1B), the magnet 913 may be positioned to face the second hall sensor 911 b or the third hall sensor 911 c. For example, if the second hall sensor 911 b or the third hall sensor 911 c senses the magnet 913, the electronic device (or the processor) may confirm an at least partially open state.

Referring to FIG. 11, at least one of switch elements 1113 a and 1113 b operating in a push type may be mounted as a detection element on the first structure (for example, the first structure 110 of FIG. 1A) or on the display (for example, the display 112 of FIG. 1), and at least one of grooves 1111 a and 1111 b may be formed as a detection target on the second plate 1121 (for example, the second plate 221 of FIG. 2). According to an embodiment, the two switch elements 1113 a and 1113 b may be mounted on the first structure, and the two grooves 1111 a and 1111 b may be formed on the second structure or the second plate 1121. As the first structure (for example, the first structure 110 of FIG. 1A) moves, the switch elements 1113 a and 1113 b may engage with one of the grooves 1111 a and 1111 b and be turned on/off. For example, in the closed state (C), only the first switch element 1113 a among the switch elements may be turned off and, in the open state (O), only the second switch element 1113 b may be turned off In some embodiments, when the first switch element 1113 a and the second switch element 1113 b are both in a turned-on state or in a turned-off state, the first structure may be in a middle state (M) between the closed state (C) and the open state (O). For example, the electronic device or the processor may at least detect the closed state or open state of the electronic device on the basis of the on/off state of the switch elements 1113 a and 1113 b.

According to various embodiments, the number and position of arrangement of the detection elements (or detection targets) described above may be diversified. For example, when a larger number of switch elements and detection targets (recesses or protrusions) corresponding to the switch elements are arranged, the exposed area of the display may be detected in a stepwise mariner It is also possible to detect the exposed area of display in a stepwise manner when a larger number of hall sensors are used as detection elements. For example, the combination of detection elements and detection targets or the number of detection elements (or detection targets) may be variously selected in view of the environment in which the electronic device (for example, the electronic device 101 of FIG. 1A) is used, the range of movement of the first structure (for example, the first structure 110 of FIG. 1), the detected position thereof, or utilization of the coordinate thereof.

Referring to FIG. 12, the electronic device 101 according to various embodiments may include a processor 1210, a display 1220 (for example, the display 112), a sensor 1230 (for example, the sensors 911 a, 911 b, and 911 c), a memory 1240, and/or structures containing the same. The structures may include a second structure which forms at least a partial area of the lower portion of the electronic device 101 and at least a partial area of the side portion thereof, and a first structure coupled so as to move (for example, slide or roll) with regard to the second structure such that at least a part of the first structure overlaps the second structure. The display 1220 may include a flexible display, at least a part of which is mounted on the first structure, and which includes a bendable portion.

According to various embodiments, when at least one structure (for example, the first structure) among the first structure and the second structure is moved (for example, slid-out, rolled-out, slid-in, or rolled-in) with regard to the other structure (for example, the second structure) in a first direction (for example, longitudinal direction), the size of the display area visually exposed to the outside of the electronic device 101, among the areas of the display 1220 mounted on the at least one moved housing (for example, the first structure), may be changed (for example, expanded or contracted). According to an embodiment, when the visually exposed display area is contracted, at least a partial area of the bendable portion may be moved (for example, slid-in or rolled-in) to a space formed by the second structure and contained therein. When the visually exposed display area is expanded, the at least partial area of the bendable portion contained in the space formed by the second structure may be moved (for example, slid-out or rolled-out) from the second structure and visually exposed to the outside. At least a part of the display area visually exposed to the outside may be retracted so as to be at least partially contained by the second structure when, for example, the first structure is moved (for example, slid-in or rolled-in). According to an embodiment, the size of the display area of the display 1220 may be changed, for example, in response to the user's direct touch input to the second structure, which is at least partially connected to the display 1220, or to an input to another feature (for example, the home button or another dedicated button) (not illustrated) arranged on the electronic device 101.

The memory 1240 may store instructions which, when executed, control the processor 1210 so as to perform various operations. For example, the processor 1210 may perform an operation of displaying at least one first object in the first area of the planar portion and displaying at least one second object in the second area of the planar portion in the closed state, and an operation of displaying the at least one first object in the first area and displaying the at least one second object in the third area of the bendable portion in the open state.

According to various embodiments, it may be determined that, when the first structure and the second structure are slide-moving with regard to each other, the size of the screen exposed in the first direction with regard to the first surface of the display 1220 is changed. The processor 1210 may determine that the screen size is changed, and may conduct a control such that designated image processing is performed with regard to the screen area which is exposed to the front surface in response to the screen size change.

According to various embodiments, the designated image processing may be performed by an image signal processor (ISP) included in the processor 1210, or may be performed by an ISP formed as a separate device from the processor 1210.

According to an embodiment, the flexible display control module 1310 may further include a screen display module 1314 (for sub-modules corresponding to remaining control operations).

According to various embodiments, if the sensor 1230 senses a screen change in response to a movement of the first structure (for example, the first structure 110), the screen change module 1311 may determine whether or not the screen is changed. The condition confirmation module 1312 may confirm conditions that are set with regard to respective areas or respective objects. For example, the condition confirmation module 1312 may confirm whether a setting has been made so as to apply real-time position compensation to a specific area or a specific object or not to apply the same. The image processing module 1313 may perform a function of processing or rendering the entire image on the basis of the confirmation made by the condition confirmation module 1312 regarding whether or not real-time position compensation is applied to each area or object.

Referring to FIG. 15 and FIG. 16, the left side indicates the electronic device 101 in a closed state, and the right side indicates the electronic device 101 in an open state. The first structure 110 of the electronic device 101 can move between the closed state (a) and the open state (b) with regard to the second structure 120 in a first direction which is parallel with the second plate and with the second sidewall 121 b, and may be positioned at a first distance from the first sidewall in the closed state and positioned at a second distance from the first sidewall, which is larger than the first distance, in the open state. The vertical length of the electronic device 101 in the open state (b) on the right side may be larger than that in the closed state (a) on the left side.

According to various embodiments, in the case of a rollable device having a display 112, at least a part of which is rolled in, a sensor 1610 may be arranged thereon so as to enable touch recognition by a touch panel. When the user expands or contracts the display, it is possible to recognize a change in the touch input coordinate in real time through the sensor 1610 and to calculate the degree of increase or decrease of the display screen size. For example, a pixel value B on the display may be determined, and the screen display module 1314 may change the configuration or layout of the screen on the basis of information collected through the sensor 1610.

FIG. 17 is a flowchart illustrating an operation of an electronic device, according to whether the display is changed to an open state or to a closed state according to an embodiment of the disclosure.

Referring to FIG. 17, the processor 1210 may sense a movement of the electronic device, an open state thereof, or a closed state thereof through at least one sensor 1610 arranged on the electronic device 101. For example, when a hall sensor 911 a, 911 b, or 911 c is sensed at operation 1710, the processor 1210 may determine whether or not the touch coordinate is changed at operation 1720.

When it is determined that the touch coordinate is changed, the processor 1210 may store an offset value which indicates the degree of expansion of the display from the default position at operation 1730.

At operation 1740, the processor 1210 determines whether or not each object constituting the screen is a graphical user interface (GUI) element to which position compensation is to be applied. Upon confirming a GUI element to which position compensation is to be applied, the processor 1210 may apply the stored offset value so as to compensate for the position of the GUI element at operation 1750. Then, the processor 1210 may control the screen display at operation 1760.

FIG. 18 is a diagram illustrating a screen of an electronic device, which is displayed according to whether the display is changed to an open state (b) or to a closed state (a) according to an embodiment of the disclosure.
